It seems like array('defaultOrder' => array('username' => backend\models\search\SORT_ASC)) of type array<string,array<string,integer>> is incompatible with the declared type boolean|yii\data\Sort of property $sort.

            'defaultOrder' => [
                'username' => SORT_ASC,
            ],
        ];
        if (!$this->load($params) || !$this->validate()) {
            return $dataProvider;
        }
        $query->andWhere(['like', 'username', $this->username]);
        return $dataProvider;
    }
